Summary
A, a New York-based autonomous offensive security startup, emerged from stealth with $37 million in funding from Lightspeed Venture Partners, Cyberstarts, and angel investors. The company uses AI to continuously break into its customers’ systems, finding real attack paths and fixing them before actual hackers get the chance. This comes as Anthropic’s Mythos model has exposed thousands of zero-day vulnerabilities, handing unsophisticated attackers a preview of what’s coming. A’s founders come from Israeli incident response firm Sygnia and Check Point, and the company is chasing the continuous threat exposure management market, estimated at $2.7 billion in 2025 and projected to reach $7 billion by 2033.

The numbers tell one story.
A’s founders, with their cyber backgrounds from Sygnia and Check Point, saw attackers begin to use AI and realized that most of what the industry had built was about to become obsolete. They created A to run the full cyber offensive lifecycle autonomously, acting like an AI-powered attacker to find weaknesses, then helping fix them before a real attacker can. Lightspeed partner Guru Chahal says the old model of paying for a manual simulated cyberattack once every six to 12 months is effectively dead. A is chasing the continuous threat exposure management market, which is projected to reach $7 billion by 2033. The company’s name represents going back to first principles—the attacker’s perspective, the root of what cybersecurity was always supposed to be.
“The gap between the time where an issue is discovered to the time you get hit with it is minutes,” Chahal said. “CISOs are terrified of this right now.”
